Among them,for primary,junior,high school and vocational high school students,the rates were 7.05%,7.06%,12.41% and 34.11%,respectively.The smoking rates were now 3.26%,with 1.99%,1.80%,3.48% and 20.22%,respectively,among primary,middle and high school and vocational high school students,male,vocational school students were more likely to report smoking across six waves of surveillance.Results from the surveillance in 2015 showed a decreasing trend in ever smoking rate and current smoking rate compared with previous survey.About half of the current student smokers were reported to take i cigarette/day,and about 10% smokers were reported to take 10 cigarettes/day.Students were most likely to smoke at home(24.02%),followed by smoking at schools(12.74%).The percentage of buying cigarettes by themselves was increased from 17.10% in 2008 to 66.09% in 2015.Conclusion From 2005 to 2015,both ever smoking and current smoking rate among middle school students in Beijing decreased in general,however smoking among vocational high school students warrants further attention.
